Measurement positions changing switch - has conductor plate below guide plate controlling contact bridge carrier

The reduced base surface measuring position switch allows a large number of sensing circuits to be galvanically decoupled, and features contact surfaces extending tangentially and radially. The main conductor plate (1) is fitted below the guide plate (5) controlling the valve-like contact bridge carrier (4). Plate (5) also holds the revolving disc (6) which has camming surfaces (6a) for actuating the contact bridge carrier. This results in contact bridges (8) pressing the contact surfaces (2). The latter are partially coated with a noble metal.
